A b b s pp r 9 bears a a t the bobbin This construction has been found to be unsatisneXt to be transferred and holds it up in pe factory, partly because of the tendency of the position in the hopper. :Quring the actual transe pins to loosen in the hopper stand and partly befer'the bobbin support yields, as shown on'Fig. 2, 20 cause of the breakage of the cast iron hopper to allow the bobbin to be moved downwardly y stands at the aperture due to the shock which the transfer hammer. accompanies transfer.
